alpha releases

Tor 0.2.2.15-alpha fixes a big bug in hidden service availability, fixes a variety of other bugs that were preventing performance experiments from moving forward, fixes several bothersome memory leaks, and generally closes a lot of smaller bugs that have been filling up trac lately.

Changes in version 0.2.2.15-alpha - 2010-08-18
o Major bugfixes:
- Stop assigning the HSDir flag to relays that disable their
DirPort (and thus will refuse to answer directory requests). This
fix should dramatically improve the reachability of hidden services:
hidden services and hidden service clients pick six HSDir relays
to store and retrieve the hidden service descriptor, and currently
about half of the HSDir relays will refuse to work. Bugfix on
0.2.0.10-alpha; fixes part of bug 1693. read more »

On August 21st we released Tor Browser Bundle1.0.10 for GNU/Linux. It includes a number of updates, the largest one being a switch to Firefox 3.6.8. The rest are:

• On July 4th, we released Tor Browser Bundle 1.3.7 for Microsoft Windows. This is a security update for Firefox and Pidgin. The changes are: update to Firefox 3.5.10 and Pidgin Instant Messenger 2.7.1r2 to fix some security issues.
• On July 6th, we released Tor Browser Bundle 1.0.8 for GNU/Linux distributions. This fixes a number of security issues with included software. The updates include:
  • Update libpng to 1.4.3 (see CVE-2010-1205)
  • Update Firefox to 3.5.10
  • Update HTTPS Everywhere to 0.2.1

New releases

• On April 24, we released Tor 0.2.2.13-alpha. This version addresses the recent connection and memory overload problems we’ve been seeing on relays, especially relays with their DirPort open. If your relay has been crashing, or you turned it off because it used too many resources, give this release a try.

  o Major bugfixes:
  - Teach relays to defend themselves from connection overload. Relays
  now close idle circuits early if it looks like they were intended
  for directory fetches. Relays are also more aggressive about closing
  TLS connections that have no circuits on them. Such circuits are
  unlikely to be re-used, and tens of thousands of them were piling
  up at the fast relays, causing the relays to run out of sockets
  and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling
  their directory fetches over TLS).

  o Minor features: read more »

Tor 0.2.2.12-alpha fixes a critical bug in how directory authorities
handle and vote on descriptors. It was causing relays to drop out of
the consensus.

Tor 0.2.2.11-alpha fixes yet another instance of broken OpenSSL libraries
that was causing some relays to drop out of the consensus.

(Windows bundles will be available whenever Andrew gets around to making
them; we're trying to stick to a policy of announcing alphas on time
rather than waiting for every package.)

Changes in version 0.2.2.12-alpha - 2010-04-20
o Major bugfixes:
- Many relays have been falling out of the consensus lately because
not enough authorities know about their descriptor for them to get
a majority of votes. When we deprecated the v2 directory protocol,
we got rid of the only way that v3 authorities can hear from each read more »

Tor Browser Bundle 1.1.6 (released December 2) and 1.1.7 (released December 12) update Tor to 0.2.1.8-alpha, include a new version of Firefox, and attempt to wrestle with the "AllowMultipleInstances=false" design that could allow us to run Tor Browser Bundle alongside a normal Firefox.
